Concept

Seidenstrasse is a pneumatic tube system built from vacuum cleaners and drainage pipe. You can send capsules through it using one of the stations located at the venue.

The current plan features a star topology of nodes in hall 2 with the central node located at our assembly. To find it, just follow the tube ;)

Architecture

There are two types of nodes: switching nodes and exit nodes.

Switching nodes are points where multiple pipes arrive and where people feel like performing the switching functions. Feel free to visit us and help us switching packets (you'll find us, just follow the yellow tubes!).

Exit nodes can be at any place in the building and can be used to send and recieve capsules. We'll provide you information howto send capsules at every station.

Numpad Usage

Enter "B" to set the location and then the destination-ID.
Enter # to send it to it's destination.

Remember: Routing is currently in debugging it may not work correctly.
There can't be two routes at the same time, since it's centraliced to 4 vaccuums.

Adressing Scheme

Each exit node is adressed by its switching node designation plus its pipe number. Each switching node handles its pipe numbering as it sees fit. Re-numbering is strongly discouraged, if pipes fail or are shut down, just leave its number dormant.

Naming Convention

The basic adressing scheme consists of the Switch Node Number followed by a : and the Endpoint Pipe Number at this node. e.g. 23: 42 (meaning: switching node No. 23, Endpoint No. 42). A barcode representation of the basic adressing scheme should be developed. Additionally, memorable naming is allowed, at least if the switching node is operated by humans.

How to make your own capsule

Everyone who wants to participate can build their own capsules. Please post your pictures, drawings, instructions and experiences here as inspiration for others.

Important: Capsules without light will not be allowed in the system! Attach at least one LED to each capsule, so stuck capsules are visible. No exceptions!

3D Files

[4] Nalgene 16oz/500ml bottles. Bring wide Mouth ones without that strap thingy to us, so we can test them. (They are the most expensive ones from all bottles. The cheapest being the 1.5 L PET.)

How to send a capsule

First, write the receiving address on the capsule (optional: return address) or use our address stickers: LINK TBD. Then bring your capsule to the nearest exit node, put your capsule in and call the nearest switching node with the phone provided at the node.
